Swift wrote that her decision to stream 1989 for the first time was not part of a larger exclusive deal with the company. Instead, she cited Apple’s recent “change of heart” with regard to how it will compensate artists during the service’s three-month free trial period.

On Sunday, Swift wrote an open letter to Apple criticizing its policy, which would have kept any revenue from artists during the first 90 days of Apple Music.

“I find it to be shocking, disappointing, and completely unlike this historically progressive and generous company,” Swift wrote in a widely circulated Tumblr post. “This is not about me. Thankfully I am on my fifth album and can support myself, my band, crew, and entire management team by playing live shows. This is about the new artist or band that has just released their first single and will not be paid for its success. This is about the young songwriter who just got his or her first cut and thought that the royalties from that would get them out of debt. This is about the producer who works tirelessly to innovate and create, just like the innovators and creators at Apple are pioneering in their field… but will not get paid for a quarter of a year’s worth of plays on his or her songs.”

In the wake of Swift’s letter, Apple changed its mind. “Apple will always make sure that artist are paid,” senior executive Eddy Cue wrote on Twitter hours after Swift’s post. “#AppleMusic will pay artist for streaming, even during customer’s free trial period.”

Swift was pleased with Apple’s change of heart. “I am elated and relieved,” Swift wrote on Twitter after the news broke. “Thank you for your words of support today. They listened to us.”
